MEANS FOR MOORING l Specification of Letters Patent. Patented Oct. 19, 1920.

Application led February 2, 1920. .Serial'Na 355,696.

To all/whom t may conce/m:

Be it known that I, WILLIAM H. WATT, a. subject of the King of Great Britain and Ireland, residing at Napier, island of New Zealand, have invented certain newand useful Improvements in Means for Mooring Airships, of which the following is a specification.

This'invention has for its object an improved meansfor mooring airships and con*- sists in the combination with a mast'of one plan,

. ployed.

Referring to the drawing, the airship l is shown moored by its nose 2 to a vertical mast 3 of any 'suitable'construction 0n the ground and laid with the base of the mast as center are a number of concentric flanged rails 4 on which engage carriers 5 provided with ball bearing rol ers 6 to run on the flanges of the rails. These rollers have their running surfaces suitably curved as shown for ease in working. The carrier'at-its upperend is arranged to'swivel about an eye bolt 7.adapted to` be connected to a shackle 8 which in turn can be connected by suitable bridles 9 tothe holding down positions' on lthe keel. Spring compression balances indicated by numeralI 10 may be provided between the carriers and the'bridles to show the tension on the bridles and if desired suitable recording Adevices may be employed with the balances to show in a hut indicated by l1 adjacentI to the mast, the various tensions in the bridles.

The bridles can be set up so as to maintainany desired angle of trim, such for eX- ample as a few degrees down by the stern,

so that the effect of a high wind on the airship riding lat such an angle would lonly tend to increase the lifting power, thereby keeping taut the holding down gear and insuring perfect safety at the stern.

By using the method as above described, an airship will remain at her moorings free from vertical movement at the stern inall weathers.

1. A means of mooring airships, comprising the combinaton of a mast to which the front end of the airship is moored, and rails concentric with and encircling-the mast and engaged byrollers connected to the holding down positions on the airships.

2. A means of mooring airs'h'ips, comprising the combination of a mast to which the front end of the airship ismoored, and rails concentric with and encircling the mast and engaged by rollers connected to the holding down positions on the airships, and a swiv-y eling connection between the rollers and the means connecting them tothe holding-'down positions. v

3. A means of mooring airships, comprising the combination of a mast to which the front end of the airship is mooredfand rails concentricwith and encircling the mast and enga ed by rollers connected to the holding own positions von the airships, and indicating means between the rollers and they holding down positions to show the pull on ythe rollers.

In testimony whereof I have signed my name to this specification. f w. H. WATT.A
